What are the common side effects of Botox?

Botox has a variety of somewhat more common and less serious side effects associated with it.

These are comprised of pain at the point of injection, a dry mouth, weariness, neck pain, headaches, eye problems, and allergic reactions that include rashes, itching, wheezing, asthma like symptoms, and feelings of faintness.

Once again, these symptoms are more likely than the serious side effects, but still uncommon.
